It is a nice bundle indeed. One workflow I found is missing, though, is Dev Doctor: http://wemakeawesomesh.it/alfred-dev-doctor

Easy to use, quick access to several languages (python, ruby, js, clojure) base documentation.

Agreed I love dev doctor, it's indispensably useful! I use it all the time.

Disclosure: personal friend wrote dev doctor.

Have yet to take a look in Julia, but I've been playing around with Elixir for a while and looks great. Elixir macros particularly got my attention:

There is a book on Elixir coming out from Pragmatic Programmers sometime and will be written by Dave Thomas, which might generate a certain buzz too. This may be a good time to dive into it a bit more.
